[jQuery] is there a way to get events to work in cross window context

In my parent window i got this in the 'onload' function. There is an
HTML iframe element with id='frame'

function init( ) {
iframeElement = document.getElementById('frame')
iframeElement.src='http://childWindowFile.php'

$(iframeElement.contentWindow).bind("LOADED", this, foo)

}
function foo( ) {
alert("I WANT THIS TO WORK");
}

In my child window i got this in the 'onload' function.

funciton init( ) {
...
...
...
$(window).trigger("LOADED");
}

This does not work, but, is there a way to get user-defined-events to
work in a similar, cross-window fashion.
